www.aga.org Note: The AGA Operations Best Practices Program is intended to highlight how particular companies may address a specific operational issue and may not include all of the data related to a highlighted practice. The need to implement and the timing of any implementation of highlighted practices will vary with each operator. Each operator serves a unique and defined geographic area and their system infrastructures vary widely based on a multitude of factors, including, condition, engineering practices and materials. Each operator needs to evaluate highlighted practices in light of their system variables. Not all highlighted practices will be applicable to all operators due to the unique set of circumstances that are attendant to their specific systems. Companies are not ranked through this program and no one practice is identified as the best for a particular topic. Copyright & Distribution: Copyright © 2014 American Gas Association.
